Four card feature section

What specific areas of your project would you like help with?

I still need help with accessibility and HTML semantics. I was trying to create something like fluid containers with as little use of media queries as possible focusing on clamp. I have created my own template in excel for this need, which once entered the minimum and maximum size and the breakpoint where the increase or decrease should start and at what size it should end. It would also be useful to help organise the variables.
